DRAFT-RIGGINGiFOR RAILWASfrCARS.

' To all whom tt'mal concern:

Be it known that I, GEORGE A.- J oHNsoN, a citizen of the United States, re siding at Chicago, in the county of Cook and State of-flllinois, have invented a certain new-and useful Improvement in Draft-Rigging for Railway-Cars, of which the following is a full, clear, concise,- and exact description, reference being had to the accompanylng drawings, forming'a part of this specification.

My invention relates to improvements in draft rigging for railway car's.

The object. of my invention is to provide a draft rigging of high compression resist- 5 is a tail showing in perspective a friction shell. Fig. 6 is a further perspective view of the friction shell 4 In the drawings 7, 7 represent draft sills.

or parts of the car frame to which the draft rigging a attached, 8 the end sill, 9 the bufler block, 10 the draw bar carry iron, 11

' the draw bar, having a transverse slot 12 to receive the coupler key 13, 14, 14 cheek plates suitably secured to the draft sills,

each being provided-with the front stop" shoulders 15, 15 and the rear stop shoulders 16', 16, and eachbeing provided with a longitudinal groove 17 adapted to receive a" limb 18 of the horizontal yoke 19.

The yoke 19 is forwardly provided with the transverse. slots 20,.20 through which the coupler/key 13 passes, and thus connects the draw bar with the draft yoke. Within the draftyoke is disposed the front follower 21 and the draft gear 22, the draft gear being supported against downward 'displacement by the tie. plate .23.

The draft sills 7 preferably comprise a pair of channel beams spaced apart, with upper and lower outwardly turned flanges 24, 24 and 25, 25 respectively, and an angle iron 26 secured to the lower edge of each of said channel beams, the lower flange 25 of each channel beambeing secured, preferably by rivets, to the outwardly turned Fig. 2 is a plan- View partly in.

Application filed March 10,1913. I serial no. 753,246.

adjacent flange 27 of the angle iron, and the'sald flanges 25 'ofeach channel beam and the flange 27 of each angle iron being perforated to receive the bolts 28 which pass througlithesame and through theends 6' of the tie plate 23. The said bolts also bear a clip 29,,which is'preferably extended along a the lengthof the tie plate 23. Each clipr-in closes the lower flange 25 of one of the channel beams, the adjacent flange 26 T of" the angle iron, and one end of the tie plate. The draft gear .22- comprises a friction shell 30, preferably cylindrical-in shape or circular in cross section, having an internal friction face 31, and being provided with a 6 preferably integral rearwardly extended loop 32. The friction shell 30 hasat its rear end a preferably rectangular plate 33, the same being preferably integral with the said shell and integral with the loop 32, 7

the said plate serving as. a rear follower, and. adapted to engage the rear stop shoul ders 16, 16 of the cheek plates.

The sprll'g loop has a transverse [opening 34, which is preferably rectangular in shape, 3

and is provided at each side in preferable construction with outwardly turned strengthening flanges 35, 35. The 1 said flanges" are connected at their rear end in preferable construction. by a plurality of 35 38, 38, preferably two in number, thesaid springs being arranged one'above the other, as illustrated in Fig. 1 of the drawings, the said springs being, seated at their rear end against the rear member 39"of the loop and at their forward ends againstthe rear face 10( 40 of a movable spring seat 41'. The said movable spring} seat is provided with an outwardly extended flange 42 adapted to engage the shoulder 37 at the rear end of the friction shell, the said spring seat being in engagement at its-forward end 43'Wltl1 the friction mechanism- 44 within the shell 32. l 1

, The friction mechanism 44 comprises aplurality of'friction shoes 45, preferably 1 14 I which spring seat with a recess 56 to receive the head 57 of spring loop 32,

three in number, in annular arrangement within the shell, each of said shoes having an outward friction face 46 adapted to engage the friction face '31 of the shell, and

each of said shoes being provided on its inner face with an anti-friction roller seat 47, within each of which is seated an antifriction roller 48-, each of said rollers engaging with the adjacent wedging face 49 ofrthe wedge or spreader member 50; The I Wedge 50" at its forward end is in engagement with the front follower 21, and is pro 'vided with recess 52 to receive the nut 53 of the connecting rod 54:, which passes through the said wedge and through a per foration 55in the movable spring seat 41, is rearwardly provided the said connecting rod.

Thelimbs 18,18 of the horizontal yoke 19 are preferablyv turned toward each other at the rearward portions thereof, as indicated at the numerals 58, 58 in Fig. The

connecting member 591 between the said limbs 18,- 18 engagesthe rear end 60 of the On forward movementof the draw bar the draft gear is drawn forwardly by means of the draft yoke against the front follower 21, thus bringing into compression resisting action the friction members within the shell 22, and the-spring 38, 38 within the loop 32.

' On rearward movement of the draw'bar the transverse plate 33 serves as a rear follower,

' being enhanced through the use of the rear wardly extended loop, which extends to a point between the draft membersback of the rear stop members, and thus enables the employment of compresslon resisting means within the loop in addition to the usual 1. In a draft gear, in combination, a friction shell, a spring loop connected to said. shell, friction mechanism within the friction shell and springs within the loop, a movable spring seat between the friction mechanism and the springs, the friction shell being rearwardly provided with a, shoulder, and the spring seat being provided with a shoulder adapted to engage therewith in normal position of the parts of the draft gear,

2. In a draft rigging, the combination with stop members, of a friction shell mounted between said stop members, the shell being provided with a loop extending to the rear of the rear stop'members, friction mechanism.within the shell, twin arranged springs within the loop, and a yoke encircling said shell and loop and arranged in a plane perpendicular to the plane of the 7 loop, said yoke having the rear portions of the arms thereof incnnedtoward each other .at the rear of the friction shell whereby the rear connecting member for the arms is shorter than the distance between the arms where the arms pass by the friction shell.

3. In a railway draft rigging, the combination with stop members, of a friction shell i having a vertically arranged loop extending from the rear thereof and to the rear of the stops, said loop being open on the sides thereof, friction mechanism within the friction shell, springs within the loop, and a horizontally anranged yoke extending around thefriction shell and the loop.
